[vtkusers] 答复: The differences about VTKData and VTK LargeData between VTK 5.10 and VTK 6.1

[Cory Quammen]

Hongsongyang,

Someone should correct me if I'm wrong, but I think all you need to do
to get the equivalent of VTKLargeData is to set the VTK_USE_LARGE_DATA
option to ON in CMake. This will enable the large data tests and will
cause the large data files to be downloaded during the build.

Thanks,
Cory
